Is that a new Javascript language term I haven't heard of? ;-)
@AdaMan82, taking @allObjects observations into account, what type of batteries are in use and what is their ampacity? How old are they should they be rechargeables? I've had a few NiMH go bad after three years of near daily use - that might be to spec however, would have to check
I recently purchased some off brand rechargeable NiCd's only to learn they only have a 600mAHr rating, when most are around 1800mAHr and I've seen some other chemical makeups with a bragging value approaching (still needs to be researched) ~3000-5000mAHr !!
I'm working on an all purpose battery pack currently considering the 18650 rather than AA
Post some parameters and the math calculations for battery longevity - a bit stymied? Both allObjects, AkosLukacs and I would love to battle that out to arrive at how your project is actually performing.
For the sleep option, which board is in the project? Post
process.envresults please.A simple FET switch might be all thats needed to turn off the juice to the Neopixel hogs or a relay as indicated in post #2 What about using a pin on the Espruino to control a Buck step-up converter that would supply the 5V? hummmmmm . . . .
